  • Patent number: 9017808
    Abstract: A method of manufacturing a thermal interface material, comprising providing a sheet comprising nano-scale fibers, the sheet having at least one exposed surface; and stabilizing the fibers with a stabilizing material disposed in at least a portion of a void space between the fibers in the sheet. The fibers may be CNT's or metallic nano-wires. Stabilizing may include infiltrating the fibers with a polymerizable material. The polymerizable material may be mixed with nano- or micro-particles. The composite system may include two films, with the fibers in between, to create a sandwich. Each capping film may include two sub films: a palladium film closer to the stabilizing material to improve adhesion; and a nano-particle film for contact with a device to be cooled or a heat sink.
